1 Product Description
The TXMC395 is a Conduction Cooled Switched Mezzanine Card (CCXMC) compatible module providing a
four channel Ethernet 10Base-T / 100Base-TX / 1000Base-T interface.
A PCIe Switch provides access to the Intel I210IT Gigabit Ethernet controllers. Each Ethernet interface
supports 10, 100 and 1000 Mbit/s transmission rates and is equipped with a 16 Mbit Serial Flash to support
PXE and iSCSI boot.
The four Ethernet interfaces of the TXMC395 are capable of performing an auto negotiation algorithm which
allows both link-partners to determine the best link-parameters. The TXMC395 supports IEEE 1588/802.1AS
Precision Time Protocol (PTP) and IEEE 802.1Qav Audio/Video Bridging (AVB) traffic shaping (with software
extensions).
The TXMC395-10R routes four Ethernet ports to the Back I/O P16 connector. Two ports are mapped in the
X12d range and two ports are mapped in the X8d range specified in VITA46.9 standard.
All ports are galvanically isolated from the Ethernet controllers and LEDs on the board indicate the different
network activities.
The module meets the requirements to operate in extended temperature range from -40°C to +85°C.
Software Support:
o Software support for Intel I210IT at www.intel.com
o For operating systems not supported by Intel, please contact TEWS.

3 Handling and Operation Instructions
ESD Protection
This CCXMC module is sensitive to static electricity.
Packing, unpacking and all other module handling has to be done
with appropriate care.
Power Dissipation
This CCXMC module requires adequate conduction cooling!

4 PCI Express Interface
TXMC395 PCI Express Device Topology
The TXMC395 uses four Gigabit Ethernet Controllers (Intel I210-IT) each communicating via a PCIe Rev. 2.1
compliant x1 Interface.
To be able to access the Ethernet controllers they are connected to the x1 Downstream Ports of a PCIe
Switch (Diodes Incorporated PI7C9X2G608GP).
The x4 Upstream Port of the PCIe Switch is connected to the host system.

5 Ethernet Interface Status LEDs
The TXMC395 provides an individual Status LED for every Ethernet Interface. Due to the fact that CCXMCs
are mounted upside-down on the carrier card the Status LEDs are visible on the back side of the TXMC395.
A marking is placed close to each Status LED to indicate the Ethernet Port it corresponds to.
See table below for more details:
Status LED Description
OFF No cable is connected or no link is established
ON A link is established
BLINKING Activity (the Ethernet Port transmits or receives data)
